Love this.
Rock and roll may well have been invented in the back of a New Orleans appliance store, by a nineteen year old who dropped out of chemistry. 🎷
His name was Cosimo Matassa. His family ran a grocery and then an appliance shop on North Rampart Street, and in 1945 Cosimo put a small recording studio in the back room. He called it J and M. It was tiny. Musicians stood shoulder to shoulder. There was no isolation, no separation, no way to fix anything later.
That limitation turned out to be the whole sound. Cosimo could not bury a bad take in layers, so he learned to capture a room of players locked together and let it breathe. He pushed the drums and the bass forward when the fashion was to hide them, and he let the horns bite. What came out was loud, warm, rhythmic and physical, and nobody else's records sounded like it.
Then look at what was cut in that room. Fats Domino's first sides. Little Richard recording Tutti Frutti in 1955, with Earl Palmer on drums inventing a way of playing that half the drummers on earth would copy. Lloyd Price. Smiley Lewis. Shirley and Lee. Later, Ray Charles, Ernie K Doe, Lee Dorsey, Irma Thomas. Session men like Palmer, Lee Allen, and Red Tyler played on so many hits that the studio band effectively wrote the rhythm of American popular music.
Cosimo himself never took a writing credit or claimed to be a genius. He described his job as staying out of the way. He was still working in New Orleans decades later, an unassuming man who had accidentally engineered the twentieth century.
There is another thing worth saying. In a segregated city in the 1950s, Black and white musicians recorded in that room together because the music required it. The room did not care.
They were making rhythm and blues for a local audience and had no idea they were building the foundation of rock and roll.
The whole world learned to move to a beat that was cut in a back room on Rampart Street. 🎹
